tun: openbsd: check for interface already being up
In some cases, we operate on an already-up interface, or the user brings up the interface before we start monitoring. For those situations, we should first check if the interface is already up. This still technically races between the initial check and the start of the route loop, but fixing that is a bit ugly and probably not worth it at the moment.
